Abstract

An adapter ( 10 ) for installing positioning elements ( 46, 48 ) on a holding rail ( 50 ) that is to be embedded into concrete has a receptacle ( 14 ) into which the holding rail ( 50 ) can be inserted, and at least one connector ( 36, 38, 40 ) through which a positioning element ( 46 ) can be installed on the adapter ( 10 ).

1 . An adapter for installing positioners on a holding rail to be embedded into concrete, comprising:
 a receptacle, the holding rail insertable into the receptacle; and   at least one connector for installing a positioner on the adapter.   
     
     
         2 . The adapter as recited in  claim 1  wherein the receptacle is U-shaped and has a base and two legs, so that the holding rail can be accommodated with a positive fit. 
     
     
         3 . The adapter as recited in  claim 2  wherein the at least one connector is provided on the base and/or on one or both of the two legs. 
     
     
         4 . The adapter as recited in  claim 2  further comprising a fastener onto which a fixater is affixed is provided on at least one leg. 
     
     
         5 . The adapter as recited in  claim 4  wherein the fastener includes two holes, and the fixater is a cable tie extending through the two holes. 
     
     
         6 . The adapter as recited in  claim 4  wherein the fastener includes a hook, and the fixater is a cover clipped onto the hook. 
     
     
         7 . The adapter as recited in  claim 6  wherein the cover is fastened to one of the legs by a hinge. 
     
     
         8 . The adapter as recited in  claim 1  wherein the connector has an undercut. 
     
     
         9 . The adaptor as recited in  claim 8  wherein the undercut is in the form of a groove, a rail, a bayonet catch or a thread. 
     
     
         10 . A holding system for positioning a holding rail to be embedded into concrete, comprising:
 an adapter as recited in  claim 1 ; and   the at least one positioner fastened to the connector of the adapter.   
     
     
         11 . The holding system as recited in  claim 10  wherein the positioner includes a rod capable of being a spacer. 
     
     
         12 . The holding system as recited in  claim 10  wherein a length of the positioner is variable. 
     
     
         13 . The holding system as recited in  claim 11  wherein the rod is installed on the adapter so as to be adjustable in length. 
     
     
         14 . The holding system as recited in  claim 10  wherein the positioner has a pedestal. 
     
     
         15 . The holding system as recited in  claim 10  wherein the adapter and/or the positioner is/are at least partially made of plastic. 
     
     
         16 . The holding system as recited in  claim 10  wherein the adapter and/or the positioning element are at least partially made of concrete or of a cement-bonded material. 
     
     
         17 . A holding system comprising:
 a holding rail to be embedded into concrete;   an adapter as recited in  claim 1 , the holding rail firmly accommodated in the adapter; and   a positioning element selected from a plurality of variable available positioning elements being installed on the adapter.
